Yokei ［余慶］ (919–991): A priest of the Tendai school in Japan. He studied the Tendai doctrine under Myōsen and Esoteric Buddhism under Gyōyo. In 989 he was appointed chief priest of Enryaku-ji, the head temple of the Tendai school at Mount Hiei. Because he was from the group of followers of Chishō, the fifth chief priest, he faced strong opposition from a rival group, the followers of Jikaku, the third chief priest. Finally Yokei resigned his post, and in 993, two years after his death, the priests of Chishō’s line moved to Onjō-ji temple. This led to a decisive schism between the two groups of the Tendai school.
